DC1083A-A - LTM4603 Demo Board | Step-Down μModule Regulator, 4.5V ≤ VIN ≤ 20V, Vout = 0.6V/1.2V/1.5V/1.8V/2.5V/3.3V/5V @ 6A

Demonstration circuit DC1083A-A features the LTM®4603, the high efficiency, high density step-down μModule® regulator. The input voltage range is from 4.5V to 20V. The output voltage is jumper programmable from 0.6V to 5V. The rated load current is 6A, but derating is necessary for certain VIN, VOUT, and thermal conditions. The LTM4603 can be synchronized to an external clock signal by applying the clock to the PLLIN pin.
